MEGA code up and running

The meshfree MEGA code (Meshfree Explicit Galerkin Analysis code) I've built from the ground up since coming to Penn State is up and running with (nearly) state-of the art in RKPM. 

​Here's a demo problem. Quasi-linear Reproducing Kernel Particle Method (RKPM) [1-3] with Naturally Stabilized Nodal Integration (NSNI) [4] for slope stability analysis. Soil is modeled with Drucker-Prager with tension cut-off.  

Variationally Consistent Integration (VCI) [5] to be added soon.
